Docker Networking Question - Outbound UDP Messages not using the Port defined by the UDP Port Rule with Bridge Networking

Docker Engine General

With Docker Desktop for Windows there is no way around the NAT:

It might work with Docker-CE in a WSL2 distribution, if networkingMode=mirrored is configured in .wslconfig in the user profile folder. Note: wsl2 networkingMode=mirrored is not the same as Docker Desktop’s host networking.

Update:
I should have mentioned two things:

  • with wsl2 mirrored mode the wsl distribution uses the same ip as the host
  • the container needs to be started with --network host, so you get rid of the NAT.

This way, the container should behave like it’s running natively on Linux, or your windows host.
